Huawei Wechselrichter und Wallbox abfrage über Modus?

[mickym]

@homewolf Ja das ist eigenartig - da das was aus der function Node rauskommt eigentlich ein String ist.

Also bei 1499 als Input kommt 10,0 als String raus?

Kannst Du mal einen Screenshot von Deiner Modbus Node machen - ich kenne die ja nicht, aber vielleicht sehe ich da Einstellmöglichkeiten - wie gesagt ich selbst habe keinen Modbus.

@mickym hinter dem Change kommt raus
13.8.2023, 23:20:31node: debug 2
hm-rega.0.28633 : msg.payload : number
1.499

[mickym]

@mickym ja das ist ja richtig

1499 W = 1.499 kW - Zahlen werden in JS immer mit Punkten und nicht mit Komma dargestellt.

[HomeWolf]

@mickym

ja scheinbar braucht aber die Ausgabe bei Modbus ein , anstelle den .

[mickym]

@homewolf Nein eigentlich nicht - ich habe mal die Nodes installiert - aber wie gesagt ich habe keine Hardware dahinter.

Und das Array passt bei 1499 als Eingabe - bekomme die gleichen Zahlen:

Die Rückkonvertierung klappt auch.

[HomeWolf]

@mickym Das kommt bei mir raus..

somit schick ich ja die Werte von Debug 2 an Modbus, dieser will aber ja 1,499 haben ... nur mit dem Wert klappt es ja.

[mickym]

@mickym Ja das sind ja die gleichen Zahlen die ich auch habe - kannst Du mal Deine Set Node exportieren und hier in Code-tags einstellen? oder welcher Code gehört zu Deinen Set Nodes?

OK - so gehts

Nee so wie vorher wars besser - aber ich habs schon.

Sehr gut

[HomeWolf]

@mickym Deine für deine Geduld... hat ein bisschen gedauert

[mickym]

@mickym Also wie gesagt - ich kanns im Moment nicht so richtig nachvollziehen - aber die Set Nodes haben unterschiedlichen Code - das ist eigentlich ein NoGo - zumindest um das nachzuvollziehen.

Oben ist Debug 100 und unten Debug 101 - welcher funktioniert nun?

[mickym]

Falls diese komische Array - als String intern konvertiert wird prüfe doch mal ob Du mit einer Inject Node mit einem richtigen Array ebenfalls funktioniert.

Also

Probiere mal direkt mit einer Inject Node in die Modbus Node zu schreiben, ob das gleiche Ergebnis rauskommt.

@mickym

Also ich habe es jetzt mal auf den Anfang zurück gebaut. Über geben wird an W L1 1499,0 und an Total W Engere L1 14,0. Das Ergebnis an der Wallbox ist 149,90 KW. Somit würde ich sagen ist W L1 der ausschlag gebende

[HomeWolf]

@mickym

wenn ich [1000,0] eingebe, kommt 100,00 kw raus...

[mickym]

@homewolf In die Inject -Node?

[HomeWolf]

@mickym
jap, also da wo du die 10 eingetragen hattest..

[mickym]

@homewolf Ok - dann passt das zumindest dass das Intern wieder als nummerisches Array behandelt wird. Das Komma in dem String halt also nichts mit einem Dezimalkomma zu tun - sondern separiert die beiden Array Werte. In Modbus schreibst Du in regel 2 unsigned Integer.

[HomeWolf]

@mickym

wenn wir vorne das Change weg machen, bekommen wir den Wert nicht hinter der Funktion durch 1000 gesetzt, so das das kommen bleibt?

[mickym]

@homewolf Das Problem ist, dass die Register nur mit Integerwerten arbeitet und nicht mit Floats. Solange Du also 1499 eingibst hast Du kein Problem. Aber 1,499 ist eben nicht darstellbar sondern wird als Integer behandelt.

Was diese Zeile macht

watts[0]=msg.payload.toFixed(0) * 10;

ist folgendes. Wenn Du 1.499 eingibst - wird das ganze gerundet ohne Dezimalstellen (toFixed(0)). Also auf 1 und dann mit 10 mulitpliziert.

Bei 1499 gibts keine Kommastellen und es wird einfach mit 10 multipiziert. also 14990. Deshalb kommt da 149,90 kW raus.

Wenn wir also 1,49kw haben wollen bzw. 1,5 kW also 1,499 auf 2 Kommastellen gerundet dann müssen wir 150 eingeben. Trotzdem werden wir ggf. Probleme bekommen. Aber ich versuchs mal mit 150 - Also 1499/1000 auf 2 Kommastellen gerundet und dann *100 - Allerdings komme ich mit dem Array noch nicht klar.

[mickym]

So ich weiß zwar nicht warum bei Dir das Integer nun le und nicht be ist aber so müsste die Umrechnung funktionieren:

Die 3 Nodes zwischen die iobroker Node und die Modbus Node klemmen. Warum das eine le und das andere be ist - keine Ahnung vielleicht ist das Hardwareabhängig.

Sprich die Nachkommastellen werden automatisch von der Hardware auf 2 Nachkommastellen fix interpretiert.

Die Summierungsfunktion ist für mich Schwachsinn. Da musst Du meines Erachtens mal schauen, ob das überhaupt Sinn macht.
